Repeat this process for the lower guide assembly. 
Note: Upper guide stud may be adjusted in or out in the guide post to allow proper clearance for 
blade, and for alignment with lower guide. 
 
 
Align backup bearing as previously described for upper guide. Tighten both set screws when alignment 
is confirmed. 
Re-adjust side rollers. (Graphic in previous column) Set the side clearance distance between rollers 
and saw blade, leaving about a .004 gap. 
 
 
Note: If the adjustment setting for side clearance 
between roller and blade is not enough, the side 
rollers will cause the blade to miss-track or be 
pushed outward from the guide rollers. 
 
Note: If blade alignment from band wheel to 
roller guides is necessary, do so by rotating 
eccentric shafts on the roller guides. Then 
lock them in place with the set screws.
 
 
After all adjustments have been made, tighten 
all components tight. 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
BAND SPEED SELECTION 
 
The saw blade is driven by a single speed transmission on the 16” machine and dual speed 
transmissions on the 24” and 40” machines. The shifting lever on the larger models has three positions. 
(Figure 1) The center being the neutral position, for set up. With the machine off, move the shift lever to 
the left for low speed range (50-500 FPM) and to the right for the high speed range. (500-5000 FPM) 
To shift the machine the shift lever handle must be pulled outward and then shifted left or right. (Figure 
2) 
WARNING: NEVER SHIFT WHILE THE MOTOR IS RUNNING. THIS WILL CAUSE EXTENSIVE 
DAMAGE TO THE DRIVE TRAIN.
